1 ,Q25,93G. Specification Application filed July 25,

Tolall whom it may concern: Bea-it known that I, WARREN R. VALEN- Tmp, residing at Ford City, in. the county of 'Armstrong and. State} Of PEIiIlSyTVIIDia, a .5 citizen of theUnited Sta tes,-have invented or discovered certain new and useful Im- *provem'ents' in Annealing '-.Leers for Glass Articles, of whichimprovements the followis aspecification. [0 If tisithe 'objectof the invention .to provide;

" an improved leer artieularly. suitablefor annealing-large. p ates ,o'r -s'heets of glass, together with Lim1proved"mechanism for transporting the p ates through the leerl.

In. the faccompanying drawings there is v villustrated-a leer .e'm bodying the invention in its preferred form. I

Figurel lis a pla-n'view of the floor of the broken T -portions oftheI-mechanism beneath. Fig. 2 is o transverse sectionalelevation I on the 1inc 11-11 of Fig. 1, looking in the direc- ,"tion of the arrow 11. Fig. 3 is a partial lon- 'itudinal" sectional elevation on. the line v II- III'of Fig.1., Fi P4 is a side eleva- "tionof the discharge en of the leer and of the mechanism for; operating the railsfor ',.-transporting the sheets. Fig. 5 is a detail 0 plan view of the motor and connections for raising and lowering the rails. Fig. 6 is a plan view, partsfheing broken away, of the mechanism for moving the rails longitudinally.- Fig. 7 is :1 sectional elevation of said rail-moving mechanism, on the line VII- 'VII of Fig.6. Figs. 8, 9, and 10 are end 'side, and Ian views respectively of one 0 the floort'iles which it. is-preferred to use in Hi e-receiving end ofthe leer. Fig. 11 is a gierspective view of oneof the connector i'strips for the tiles. I The annealing-chamber is continuous, but by reason'of the construction of the floor preferred tov be employed at the receiving 1' end, it 'ispreferred to call said receiving .end'the receiving-portion A, while the rest oft-he-chamber is called the main-portion B. It is preferred to make .thereceivin -p 0rti0r\ A of a lengt'h sufficientto aecommofate three sheets of glass lying side by side, say fifty feet, while the portion B will be of sutlicieut length to properly complete. the annealing of the. glass, say six hundred feet or :more. Only the opposite ends of the por- 5 tion are ShO ii in the drawing Patented Ma 7, 1912. 1910. Serial Iio. 573,586.

' The of the leer my. be built of brick, having the supporting 'eams 1', crossrails 2 and plates 3. Longitudinal supporting-wallsAniay also be provided beneath the structure which will be otherwise open underneath for convenient-access. \Vithin thebrickwork immediately beneath the annealing chamber are longitudinal heatingfiues 5,each of which is connected at the entrance end, as by a pamagc 6,"with 'a source of supply of gaseous fuel, not shown. The'heating-flues preferably extend the entire lengthof the leer, being connected at ornear the exit end to a stack-flue, not shown. Underneath the, chamber at-the entrance end is a. sand-piti7, having a'cover 8, and connected by a passage or passages '9 with the transverse slotlO atthe entrance to the chamber. v 1

The fioorof the receiving portion A of the chamber is preferably constructed .of the tiles ll'and connector-strips 12/ As shown notches 13 inits top face at its opposite ends, to receive the eiids ofthe connector-strips.- The tile is cut away longitudinally-alqng-its top side edges to form semirgrooves 15;,- which are connected at their center, by vertical-marginal ooves '16, with the transverse channel 1 formed in theunder face of the tile. The tiles are-laid sideb'y side in transverse rows the spaces between the rows being'bridge by the conncctor-stri s 12, having their'opposite ends fitted into t e notches 13in the ends of the tiles in adjacent rows, .and'r'the -joints being packedjwith asbestos-if desired. The semi-grooves .l5- -in -,f6rin". the ,rlongit'udinzil grooves '18 for the movable glass-transporting rails to be pres- 'ently described, while the transverse cha n. .nelsundernea-th form a 'coxitinuousopenconnected by the vertical passages 16 with the grooves 18 in the upper; face of the floor, for the deposit of sand and particles of glass, which may be blown out from the ends of the channels when desired.

shafts 20. These shafts project through the side-walls of the chamber, and 'may have hearings in supporting-stands '21. Upon the rock-shajts iu, the-spaces between the conin Figs. 8, 9, .and' 10, each of the tiles has.

ended-channel 19 beneath each row of tiles,

the'lsi des of the adjacent tiles in each row Running; transversely of the chamber, in the spaces'between the rows-of t-ilesand un dernea-th the connector-strips, are the rock-- nector-strips and in lin'e lwit-h the 18, are fastened .the armsy22 carrylngthe sheaves 23. The 'peri heriesl'of these sheaves are-suitably groov' :0 receive somewhat loosely the movable .glass-transportingt-mils 24. The rails 24 extend the entire length of the annealing-chamber, and pro'ectjout' :a1, 32, 33, 34, with the crank-shaftestate.

ing a connectingrodflti, the opposite end of which is connected to-the arm 37 fastened to the rock-shaft 38. The rock-shaft 38 is con -nected, as by an arm 39, to the connectingi-od 27. Thus the operation of the. motor in opposite directions will alternately elevate and lower all the shcaves and the rails 24 in unison throughout the apparatus. The

r'och-shafts 2O are-preferably provided at "their opposite ends with weighted arms 40,

th assist in elevating the rails.

iIntermediate supports are preferably provided at intervals for the rock-shafts 20. These supports consist of stands 41 ad just- ,i ii bly mounted upon supports 42, which are *4, as shown in Fig. 3. lhe stands -H project shp'ported beneath the brick floor (if theanhell ng-chamber, in some cases upon beams ,43 and in others upon the longitudinal walls upwardly through open iron boxes -14 titted in the brick-work between the tines 5, (see Fig. l), and are provided at their upper ends with bearings for the rock-shafts 20. The stands are. loosely packed in the boxes with asbcstos, and are free to more therein with the expansion and contraction of the floor of the annealirig-chamber and the :tp paratus therein. For' that mrposo the stands are preferably connected to the sup- )orts 42 by a-ball and socket jointeflfld are adjustable vertically by means of the' serews gg' having jam-nuts 46. The stands 21 may made veftically-adjustable in the same wax.

fter the-sheets of glass have passed tion -Bfixed rails 47 may be provided he-' through the receiving-portion A of the annealin -chamber, they will have still't-ncd to sup 8. degree that the tile floor is no longer necessary. Hence in the main-portwecn the movablerails 9.4, to supportthe glass sheets.

Fastened upon this. 7 ea rriage are the vertical standards (32, which project upwardly between the -li.\ed-rails, and to which are fastened the ends of the. :96 movable rails 24. Upon the; carriage-61 is mounted the motor 63, whiehserves to drive" the carriage longitudinally along the frame. For this purpose the motor-shaft may have a worm meshing with a, worm-wheel, both m invio-"ed within the casing 64. -the wormwht-el being fastened to the transverse shaft .\t the opposite ends of the shaft 65 are pinions 36.- meshing with longitudinal Thus by o 'lerating the motor (:3 the r.- riage will he moved longitudinally along the frame, and tllt jllfiVillllt. rails ll, whichextend the entire length of the. annealing- 11'} required distance. ,Stops 68. maybe provided on the rails 55). to limit the movement of the carriage. The free ends of the movable rails 24 at the receiving/and are pref-. erabl y ta pered or pointed, in order that they may easily enter the grooved sheaves in their forward movement. i The operation of the apparatuswill apparent to those skilled in the art. Assulning the leer to e empty, and the rails 34 to be in forward and lowered position. a sheet. of glam is moved from the tt-mpering'ovcn, indicated at C, Fig. 3, and laid 'npon the floor within the annealing-elnnnber and oven the ends'of the ,rails. The motor 28 is then, 125 operated, elevating the frame 56 and the railsythus lifting the sheet of'glass ofl the floor. The motor 63 then operated, and the rails with thesheet of glass upon them shifted baclnva rtily for a distance a littloBQ mszigisa gmmur tlmi: l'lw width of? he wheat.
